Medical Assessment Disputes in NSW CTP Claims

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

If you're involved in a motor accident in NSW and facing a dispute over your medical assessment, understanding the rules and avoiding common mistakes is crucial. Medical assessments are a key part of determining your compensation under the Compulsory Third Party (CTP) scheme. However, errors in how these assessments are conducted or documented can delay or reduce your claim.

Key Rules Behind Medical Assessment Disputes

Under the Motor Accident Injuries Act 2017, medical assessments must be conducted by a registered medical practitioner and follow the guidelines set by the State Insurance Regulatory Authority (SIRA). SIRA outlines that assessments should be based on clinical evidence and must not be influenced by external factors. If a dispute arises, SIRA will review the assessment to ensure it meets these standards.

Common Mistakes to Avoid

  1. Incomplete or Delayed Documentation: Failing to provide all medical records or delaying submission of documents can lead to disputes. Ensure you keep detailed records of all treatments, appointments, and communications with healthcare providers.
  1. Ignoring SIRA Guidelines: SIRA provides specific criteria for assessing injuries. For example, threshold injuries must meet certain neurological or functional criteria. If your assessment doesn't align with these, it may be challenged.
  1. Not Seeking Independent Review: If you disagree with a medical assessment, you can request an independent review through SIRA. This process involves a second medical practitioner evaluating the original assessment.
  1. Overlooking Time Limits: There are strict time limits for submitting claims and disputing assessments. For instance, you must notify the insurer of your claim within 90 days of the accident. Missing these deadlines can result in your claim being rejected.

Practical Steps to Take

  • Obtain a Detailed Medical Report: Ensure your treating doctor provides a comprehensive report outlining your injuries, treatment, and prognosis. This report should include specific clinical findings and reference the Motor Accident Guidelines.
  • Preserve Evidence: Keep all medical records, accident reports, and correspondence with insurers. These documents are essential if a dispute arises.
  • Seek Legal Advice Early: If you're unsure about the medical assessment or the claims process, consult a solicitor. They can help you understand your rights and ensure your claim is handled correctly.

How SIRA Handles Disputes

SIRA has a structured process for resolving medical assessment disputes. If a dispute is raised, SIRA will review the assessment and may request additional information from the medical practitioner. In some cases, SIRA will appoint an independent assessor to review the case. It's important to note that SIRA's decision is final and binding.

Example Scenario

Consider a claimant who suffered a soft-tissue injury after a car accident. The initial medical assessment did not meet the threshold injury criteria under the Motor Accident Guidelines. The claimant disputed this by providing additional evidence of neurological symptoms. SIRA reviewed the case and found the initial assessment was incorrect, leading to a revised evaluation.

When to Seek Advice

If you're facing a medical assessment dispute, it's essential to seek advice from a solicitor experienced in NSW CTP claims. They can help you navigate the process, challenge incorrect assessments, and ensure your claim is processed fairly.

Next Steps

Understanding the rules around medical assessments is vital to protecting your claim. Avoid common mistakes by documenting everything thoroughly, following SIRA guidelines, and seeking legal advice when needed. If you're in Bankstown or another part of NSW, contact a solicitor to discuss your specific situation.
